FYI, there is missing removal of runtest/connectors [1], which can break some

Kind regards,

> ===========================

> Kirk was updated to v1.2

> This version brings the following updates:

>  - warning message when SUT doesn't support parallel execution
>  - more stable epoll() communication with LTX
